Freeze de Windows après mise en veille WIN32K_POWER_WATCHDOG_TIMEOUT

Hello la commu,

Depuis plusieurs mois, il arrive très fréquemment à mon PC portable (Asus UX430UQ) de freezer après la mise en veille.
Plusieurs cas se présentent lorsque je tente de le sortir de veille (ouverture du capot ou bouton power) :
-soit le PC s'éveille sans problème (50% du temps)
-soit le PC s'éveille mais après 10 à 30 sec d'écran noir (40% du temps)
-soit le PC freeze totalement : il redémarre tout seul après 2min ou écran bleu (10% du temps)

J'ai récupéré les WhoCrashed des derniers écrans bleus :
